Tru-maxx TM-DHI5A422R-ND Abrasive Oval Cone Type 18 16 Grit

Product Description

The TRU-MAXX TM-DHI5A422R-ND is a Type 18 abrasive oval cone designed for aggressive material removal on metal and weld surfaces. Constructed from zirconia alumina with a 16-grit coarse grade, this mounted point delivers fast stock removal and extended wheel life in demanding grinding applications. It is rated to a maximum of 24,192 RPM and accepts a standard 5/8-11 arbor thread, making it compatible with common angle grinders and die grinders used in fabrication, maintenance, and surface prep work. Metalworking professionals and maintenance technicians are the primary users of this type of abrasive.

This oval cone is suited for weld blending, deburring, and surface conditioning on ferrous and non-ferrous metals. The coarse 16-grit cut is best applied where fast material removal is the priority over surface finish. Typical install scenarios include heavy fabrication shops, structural steel work, pipe grinding, and industrial maintenance environments where consistent, repeatable stock removal is required on irregular or contoured surfaces.

Installation Notes

Mounting and removal of abrasive cones should be performed by a qualified operator with the grinder fully powered off and disconnected from its power source. Verify that the tool spindle speed meets or does not exceed the 24,192 RPM rating stamped on this product before mounting. Inspect the abrasive cone for cracks or chips before each use and discard if damage is found. Always install the proper guard for the tool and abrasive type per ANSI B7.1 safety standards.
